Abstract: Reliable estimates of discharge capacity in open channels are essential for the design, operation and maintenance of open channels, and more importantly the prediction of flood, water level management, and flood design. The methods of discharge estimation that are used in the available river modeling software are principally based on historic handcalculation formulae, with little or no account taken of the more recent advances in knowledge and understanding. The paper describes some of the conclusions of predicting discharge in meandering and straight compound channels with the proposed method by authors, the diversity of current knowledge and the outline of the targeted program of research that is now underway to produce an improved discharge estimation system. Particular issues of concern are the effects of the interaction between river channels and flood plain.
